Ben Chorin added: “We enter 2019 with a solid cash position of $53.2 million and a debt-free balance sheet. One of our potential key upcoming milestones this year is the planned filing of a U.S. NDA for TALICIA® in the first half of 2019, which is expected to support a potential commercial launch in the fourth quarter of 2019, subject to FDA approval. Additionally, we expect to meet with the FDA to discuss the development path to potential approval of RHB-104 for Crohn’s disease following the positive Phase 3 study results. We also plan to initiate a pivotal Phase 3 study with RHB-204 for potential first-line treatment of pulmonary nontuberculous mycobacteria (NTM) infections, an orphan disease with a strong unmet medical need, in the second half of 2019.”

“We continue to strengthen our commercial management team with senior industry executives and are pleased to have Rick D. Scruggs, a former senior executive at Salix Pharmaceuticals, expand his role as chief operating officer, U.S. operations to lead our growing U.S. commercial operations. For 2019, our established sales team is positioned to drive revenue growth with a lineup of four commercial products. In an effort to drive additional revenue growth and further leverage our existing U.S. commercial operations, we continue to evaluate opportunities to in-license and acquire additional U.S commercial products,” concluded Mr. Ben Chorin.

Select 2018 operational highlights:

TALICIA® (RHB-105)2- Eradication of H. pylori InfectionFollowing the positive results from the confirmatory Phase 3 study with TALICIA® for eradication of H. pylori infection (ERADICATE Hp2 study), RedHill plans to submit a New Drug Application (NDA) to the Food and Drug Administration (FDA) in the first half of 2019, with eligibility for six-month priority review and potential U.S. commercial launch in the fourth quarter of 2019, subject to FDA approval.

RHB-104 - Crohn’s DiseaseThe first Phase 3 study with orally-administered RHB-104 for the treatment of Crohn’s disease (MAP US study) successfully met both its primary endpoint and key secondary endpoints and confirmed the broad benefit of RHB-104 as an add-on therapy to standard-of-care treatments for Crohn’s disease. RedHill continues to assess additional data from the positive study as it becomes available and plans to meet with the FDA mid-2019 to discuss the development path towards potential approval.

RHB-204 - Pulmonary Nontuberculous Mycobacteria (NTM) Infections A pivotal Phase 3 study with RHB-204 for the treatment of pulmonary nontuberculous mycobacteria infections is expected to be initiated in the second half of 2019, subject to completion of the ongoing supportive non-clinical program and additional input from the FDA. The study is intended to assess the efficacy and safety of RHB-204 and potentially support its approval as a first-line treatment for pulmonary NTM infections caused by Mycobacterium avium complex (MAC).

BEKINDA® (RHB-102) - Gastroenteritis and Gastritis and Diarrhea-Predominant Irritable Bowel Syndrome (IBS-D)Following the successful completion of a first Phase 3 study with BEKINDA® for gastroenteritis and gastritis and guidance provided by the FDA, RedHill is currently working to design a confirmatory Phase 3 study to support a potential NDA for BEKINDA® for acute gastroenteritis and gastritis.

RedHill held a positive end-of-Phase 2/pre-Phase 3 (Type B) meeting with the FDA discussing the clinical and regulatory pathway towards potential U.S. approval of BEKINDA® for the treatment of IBS-D. RedHill is currently finalizing the design of two pivotal Phase 3 studies with BEKINDA® for IBS-D.

YELIVA® (opaganib, ABC294640) - CholangiocarcinomaThe ongoing Phase 2a study evaluating the activity of orally-administered YELIVA® in advanced cholangiocarcinoma (bile duct cancer) achieved its pre-specified efficacy goal for the first stage of the two-stage study design and advanced to its second stage. Enrollment of the full cohort of 39 evaluable patients is expected to be completed in the second half of 2019.

RedHill expanded its leadership team with the appointment of Rick D. Scruggs as chief operating officer, U.S. operations. With more than 25 years of experience in the pharmaceutical industry, Rick has extensive experience in commercial operations and business development, having served as executive vice president of business development at Salix Pharmaceuticals, Inc., up to its acquisition by Valeant Pharmaceuticals International, Inc. (now Bausch Health Companies Inc.).
